Description

Fixes a cluster of replication and race condition bugs that affect clients joining heavily modded Satisfactory dedicated and listen servers.

To improve join stability, the mod forces net updates on critical subsystems during connection to avoid replication starvation. It prevents movement freezes caused by MOVE_None resets and fixes UpdateMovementModeOnRespawn issues that leave players unable to move.

This is a pure runtime patch with no content changes and no impact on save files. It is safe to add or remove at any time. The internal module name remains SinkSubsystemRaceFix to preserve save and version link.

As of now the mod mainly lets you join otherwise impossible to join servers and increases the bandwidth of replication so you can load into bigger saves in multiplayer without major desync.

Frequently Asked Questions

Server Join Race Fix not working after update – what to do?

After a Satisfactory update, mods need to be updated. Check ficsit.app whether Server Join Race Fix has been updated for the new game version. With Mado Hosting: open the mod manager and click "Update All". If the mod hasn't been updated yet, temporarily remove it so the server starts.

Server Join Race Fix causing crashes in multiplayer – solution

Most common cause: all players must have exactly the same mod version installed. Check server logs for "ModMismatch" or "Version Conflict". Ensure all players use Server Join Race Fix v1.7.3 and the same SML. With Mado Hosting, Satisfactory servers run with 8 GB RAM for stable multiplayer performance.

Is Server Join Race Fix compatible with other Satisfactory mods?

Server Join Race Fix uses the Satisfactory Mod Loader (SML). Generally, SML-based mods are cross-compatible, but mods modifying the same game systems can cause conflicts. Test new mod combinations on a backup save. The Mado dashboard automatically detects known conflicts and warns you.
